func_brush not casting shadows

I need something to cast a shadow, and be both transparent and not solid.

I am trying func_brush but it is not casting shadows. Collision
needs to be set to never solid and I have the disable shadows set to
no, yet I am getting no shadows. Also, when the brush is set to
solid, it is still not casting shadows. I've remade the brush
several times and even tried it on another computer, still nothing.

Any input is appreciated.

make a func_brush and cover it with the block_light texture.

you have the same topic right below this one, answered.

Quite.

You can also use the brush entity func_illusionary if you're feeling particularly lazy.

Maybe I should have been more clear. I have tried it with the
block light texture and I have tried the func_illusionary entity as
well. Trust me, I'm not that lazy nor am I that stupid. The
problem is baffling to myself and my colleagues.

Err, the "lazy" comment wasn't meant to be an insult.. But anyway:
upload your VMF (or make a small test map with the same conditions) and
I'll take a look. I can't really imagine what's going wrong, other than
RAD not running or the shadows being very faint.

A normal, non-entity brush textured with the toolsblocklight texture WILL block light and cast shadows. If you don't think that it is, then that's either because you have other stronger lights in the area that are swamping out shadows, or that your light isn't being cast that far, or that you're not running RAD and there are no shadows anywhere in your map.

Trust me, this texture works, and if doesn't seem to then there's something else wrong.
